A brief outline:
Lecture
  • Definition of machining. Chipless forming as alternative to machining.
  • Cutting tools. Types and characteristics.
  • Tool materials. Coatings.
  • Kinematics of cutting process. Cutting conditions: cutting speed, feed rate and the depth of cut.
  • Machining process: formation and classification of chips, built-up edge of tool, heat and temperature in cutting, cutting fluids.
  • Tool wear. Tool life curve.
  • Selection of cutting speed, feed rate and the depth of cut depending on production rate, costs, tolerances and stage in cutting.
  • Cutting economics. Production rate vs cutting speed curve and machining costs vs cutting speed curve. Machining costs vs tolerance curve.
  • Cutting machines: types and application.
  • Finish machining: grinding, honing, lapping, polishing. Advanced machining techniques: electrochemical erosion, laser and water jet cutting.
  • Manufacturing of spur, bevel and worm gears.
  • Casting process. Moulding box, moulding material, flask, core and core box.
  • Casting materials.
  • Classification of casting processes.
  • Design requirements of casting (draft, the gating system, parting surface, shrinkage).
  • Basic of welding. Welding joint.
  • Different materials weldability depending on the type of welding process. Welding defects: main causes, type of cracks, distortion.
  • Classification and industrial application of gas and arc welding.
  • Electric resistance welding, laser beam welding, plasma arc welding and electron beam welding.
  • Soldering, brazing and adhesive (gluing).
  • Design of welding joint.
  • Short theory of plasticity and metal forming. Typical stress vs strain diagram with various stages of deformation. Flow curve. Temperature in metal forming: cold, warm and hot working.
  • Forging, rolling, sheet metalworking: bending, deep drawing and shearing (die cutting), press forming.
  • Forming machines (rolling mill, forging machine, pres, drawing machine, swaging machine). Design of forming manufacturing system (groups of machines or production line). Materials for forming tools. Occupational safety and health.
  • Forming manufacturing process documentation. Examples of forming manufacturing processes.
